Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed July 17, 1912. Serial No. 710,036.

To all whom it may concern:

Be it known that I, FREDERICK B. MILES, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Metallic Ties for Railways and Fastening Devices Therefor, of which improvement the following is a specification.

My invention relates to improvements in metallic ties for railways, and in meansto insulate the rail therefrom.

The object of my invention is to produce a metallic tie, a rail fastening device, and means to insulate the rail, which isadapted to use without spikes or bolts.

I accomplish the object of the invention by means of the device hereafter specifically described, reference being had to the accompanying drawings, in which- Figure 1 is a plan view partly in section of rail, showing the application of my invention thereto. Fig. 2 is a section on line A, A of Fig. 1. Fig. 3 is a perspective view partly in section of a rail and tie with my improvement applied thereto. Fig. 4 is a plan view partly in section showing a modified form of tie.

Referring to said drawings, 1 is a tie,

which may be constructed of metal or other suitable material, and is provided with grooves 2, 2, extending transversely thereof at both ends, in which the cylindrical portions 3, 3 of the fastening devices are seated. The said fastening devices comprise also the hooked flanges 4, 4, which are coincident in length with the width of the tie and are adapted to engage over the outer edges of the base 5, 5 of the rail 6, as shown in the drawings. Insulating material 7, as, for instance, fiber, asbestos, or other suitable substance, surrounds the cylindrical portions of the fastening devices, being secured in the recesses 8, 8, formed in the walls of the grooves.

It will be noted that the portions of the fastening devices approximating the center of the rail are slightly higher than the portions immediately under the outer edge of the web of the rail, so that pressure upon the rail tends to force the inner portions of the fastening devices downward at w, 02, thereby giving a slight rotary movement to topics of this patent may be obtained for the cylindrical portions and causing the hooked flanges to be thrown into tighter contact with the web of the rail.

The tie may be formed as shown in Fig. 4 for the purpose of producing sinuosities, which when the ballast is tamped therearound tends to hold the tie against longitudinal movement.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a metallic tie and rail fastening device, the combination of a tie having transverse grooves at the ends thereof and fastening devices comprising a plurality of cylindrical members seated in said grooves, the upper side of each of said members being a flat surface for the reception of the base of the rail, and a hook projecting therefrom adapted to engage opposite sides of the base of the rail and to be tightened thereupon by pressure on the rail.

2. In a metallic tie and rail fastening device, the combination of a rail, a tie having grooves transversely thereof at each end, fastening devices comprising cylindrical members seated in said grooves, having hooked flanges adapted to engage over the outer edges of the base of the rail, in combination with insulating material surrounding the cylindrical portions of said fastening devices.

3. In a metallic tie and rail fastening device, the combination of a rail, a tie having grooves transversely the same at both ends thereof, fastening devices comprising cylindrical members adapted to be seated in the said grooves, having hooked flanges adapted to engage the edges of the base of the rail, and a seat for the reception of the base of the flange, the inner portion approximately beneath the center of the rail being slightly higher than the outer portion thereof, in combination with insulating material surrounding said cylindrical portions of said fastening devices.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

FREDERICK B. MILES.
